Thalamic and cerebral cortical hyperperfusion on ASL in patient with separate two NCSE episodes. a, b Episode 16; c, d Episode 17. a EEG showing apparent spatiotemporal evolution from the left frontal to left temporo-parietal regions. b ASLshowing left hemispheric cortical hyperperfusion (white arrows) without thalamic hyperperfusion. c EEG showing bilateral 1 Hz periodic discharges with right hemispheric predominance. d ASL showing bilateral thalamic hyperperfusion (yellow arrowheads) and left fronto-temporal cortical hyperperfusion (white arrows).
